RTCA / EUROCAE activities include participation from the entire aviation community: ANSPs, AIS and MET service providers, national and international regulatory authorities, data link users, manufacturers and system designers, airframe representatives, and airlines


27

RTCA SC-206 / EUROCAE WG-76AIS & MET Data Link Vision:

Provide timely, accurate, and authoritative AIS / MET data to any user, anywhere, at any time, using data linkProvide “Gate-to-gate” (airline) and “Chock-to-chock” (GA) data servicesUpdate onboard databases from authoritative source(s) using data link

Data rendered onboard aircraft into meaningful depictions prior to departure and during flightData also suitable for use by onboard automation systems, including aircraft’s Flight Management System (FMS)

AIS & MET data link supports ground-to-air, air-to-ground as well as air-to-air connectivity

(Agreed to in principle, August 2009. Work presently on hold pending sponsor identification and deliverable definition)

SAE G-10 has been asked to provide timely AIS & MET HF guidance to SC-206

32

The Challenges Authoritative Data Source

Authoritative data source as a key-enablerAccurate, up-to-date and quality assured information and data

Adoption and maintenance of a common data formats for both aeronautical information and weather exchange models (AIXM & WXXM)Development and harmonization of standards and initiatives

Leverage ICAO and WMO process to achieve global convergence of standards and practicesConsistency needed between the regulatory approach and industry standards and developments


33

The Way ForwardSWIM governance and data quality standards like the European ‘‘Aeronautical Data Quality ImplementingRule’’Continued AIXM and WXXM exchange model development and maintenanceCompletion and harmonization of ongoingstandardization activities (e.g., within EUROCAE / RTCA, ARINC, SAE, ICAO, WMO)Pursuit of AIS and MET initiatives within regionallycoordinated R&D programmes (e.g., SESAR and NextGen)Reference data management systems at source level
